SNMP configuration
This section explains how to use the SNMP on the network camera. The Simple Network Management Protocol is an application layer protocol that facilitates the exchange of management information between network devices. It helps network administrators to remotely manage network devices and find, solve network problems with ease.
The SNMP consists of the following three key components:
1. Manager: Network-Management Station (NMS), a server which executes applications that monitor and control managed devices.
2. Agent: A network-management software module on a managed device which transfers the status of managed devices to the NMS.
3. Managed device: A network node on a managed network. For example: routers, switches, bridges, hubs, computer hosts, printers, IP telephones, network cameras, web server, and database.
Before configuring SNMP setting on this page, please enable your NMS first. Enable SNMPv1, SNMPv2c: Select this option and enter the names of Read/ Write community and Read Only community according to your NMS setting. Enable SNMPv3: This option contains cryptographic security, a higher security level which allows you to set the Authentication password and the Encryption password.
• Security name: According to your NMS setting, choose Read/Write or Read Only and enter the community name.
Configuration
IEEE 802.1x
Enable this function if your network environment uses IEEE 802.1x which is a port-based network access control. The network devices, intermediary switch/access point/hub, and RADIUS server must support and enable 802.1x setting.
The 802.1x standard is designed to enhance the security of local area networks, which provides authentication to network devices (clients) attached to a network port (wired or wireless). If all certificates between client and server are verified, a point-to-point connection will be enabled. If authentication fails, access on that port will be prohibited. 802.1x utilizes an existing protocol, the Extensible Authentication Protocol (EAP), to facilitate communication.
Please follow the steps below to enable 802.1x setting:
1. Before connecting the camera to the protected network with 802.1x,
please apply a digital certificate from a Certificate Authority (ie. MIS of your company) which can be validated by a RADIUS server.
2. Connect the camera to a PC or notebook outside of the protected LAN. Open the configuration page of the camera as shown below. Select EAP- PEAP or EAP-TLS as the EAP method. In the following blanks, enter your ID and password issued by the CA, then upload related certificate(s). 3. When all setting are complete, move the camera to the protected LAN by
connecting it to an 802.1x enabled switch. The devices will then start the authentication automatically.
QoS (Quality of Service)
Quality of Service refers to a resource reservation control mechanism, which guarantees a certain quality to different services on the network. Quality of service guarantees are important if the network capacity is insufficient, especially for real-time streaming multimedia applications. Quality can be
Configuration
The following are the main benefits of a QoS-aware network:
The ability to prioritize traffic and guarantee a certain level of performance to the data flow.
The ability to control the amount of bandwidth each application may use, and thus provide higher reliability and stability on the network.
Requirements for QoS:
To utilize QoS in a network environment, the following requirements must be met:
• All network switches and routers in the network must include support for QoS.
• The network video devices used in the network must be QoS-enabled. CoS
IEEE802.1p defines a QoS model at OSI Layer 2 (Data Link Layer), which is called CoS, Class of Service. It adds a 3-bit value to the VLAN MAC header, which indicates prioritization from 0~7 (Eight different classes of service are available). The priority is set up on the network switches, which then use different queuing disciplines to forward the packets.
Please follow the steps below to enable CoS settings: 1. Click Enable CoS
2. Enter the VLAN ID of your switch (0~4095) 3. Choose the priority for each application (0~7). Note:
Configuration
QoS/DSCP
DSCP-ECN defines QoS at Layer 3 (Network Layer). The Differentiated Services (DiffServ) model is based on packet marking and router queuing disciplines. The marking is done by adding a field to the IP header, called the DSCP (Differentiated Services Code Point). This is a 6-bit field that provides 64 different class IDs. It gives an indication of how a given packet is to be forwarded, known as the Per Hop Behavior (PHB). The PHB describes a particular service level in terms of bandwidth, queuing theory, and dropping (discarding the packet) decisions. Routers at each network node classify packets according to their DSCP value and give them a particular forwarding treatment. For example, how much bandwidth should be reserved.
Quality of Service refers to a resource reservation control mechanism, which guarantees a certain quality to different services on the network. Quality of service guarantees are important if the network capacity is insufficient, especially for real-time streaming multimedia applications. Quality can be defined as, for instance, a maintained level of bit rate, low latency, no packet dropping, etc.
Configuration
Motion can be detected by measuring change in speed or vector of an object or objects in the field of view.
Enable Motion Detection: Select this option to turn on the motion detection feature.
Window Name: Create your own name for the monitored area/ window. It will show at the top of the motion window.
Sensitivity: Set the measurable difference between two sequential images that would indicate motion.
Percentage: Set the amount of motion in the window being monitored that is required to trigger a motion detected alert. If this is set to 100%, this means that motion must be detected within the whole window to trigger a snapshot.
Note: Setting a higher sensitivity and a lower percentage will make motion easier to be detected.
New: Click to add a new window. A maximum of three motion windows can be
opened simultaneously. Use your mouse to drag the window frame to resize or the title bar to move. Clicking on the ‘x’ at the upper right corner of the window will close the window.
